Good to Go

Edit: Because of the developer’s response, I am changing my review from 4 stars to 5. This app has everything I am looking for- It is FOSS, it has a great user interface, you can import, export, cloud sync your seeds, and backup offline. You can also sort your seeds alphabetically or manually, which serves the same purpose as a “favorite” button. The fact that it is open source is a HUGE plus. Hopefully this app sticks around for a while and remains FOSS for the duration. If you need cross-platform non-mobile support, there is a browser extension too.

I’m searching for a Raivo replacement. 2fas is pretty good. It has a nice user interface and is intuitive to use. It doesn't have a lot of extras that would cause it to be less user friendly. I would suggest it with a slight caveat. One thing I like about Raivo is the way it uses standard zip files for its backup export. In that folder it creates to files; a json and a html. So, I can unzip the export on my computer and print either one for a paper backup I put in my safe. 2fas uses a .2fas file extension in its export. This means there isn’t a quick way change 2fa apps unless your next app choice has the ability to import a 2fas backup. Which by the way 2fas can import and/or gives instructions how to import from Google, Raivo, etc. which is pretty nice.

Developer Response ,

Thanks for the feedback, but there is a slight misunderstanding. The .2fas file our app generates is a .json file, therefore all the apps that support the .json files will be able to import our file without a problem. 😁

Fantastic 2FA app

No account sign up required, lightweight, functional, good design, and iCloud sync so your tokens are securely backed up. There’s not much more to say. The app has frequent updates for new features/bug fixes. For example, I experienced the iPad Face ID bug, it was promptly fixed in a couple weeks. One suggestion, include an option (or make it the default option) to require Face ID authentication every time you open the app when it’s enabled. Right now, if you authenticate through Face ID, it allows anyone to open the app for an undisclosed amount of time. My current workaround is to force close the app after I copy my token. Keep up the good work.

Developer Response ,

Thank you for the feedback and the review! I'll forward what you said about Face ID to the dev team and we'll look into it. 😊

Update request. Read the reviews and let us know how things are going.

The reviews were perfect. Pointing out issues a new client will have and then addressing the issue turns this into a help feature. People need full service. The world that shunned technology is running this way. Let this be a lighthouse app. One that offers assistance to all the crazy people that don’t know that their adhd is preyed upon by ads. Showing the progress of the people and the issues they were having. Showing us the value of a place where sharp people are drawn to shore safely by shedding light on impending danger. I’m a flesh and blood, living, breathing human being. That means I’m weird, confused, and making progress because I made it here. For some people, this is progress. I am some people. I went ahead and shared the rough draft. However, this is my review of the comments since I haven’t decided on an app yep. Thanks in advance;) Give us an update of what can we look forward to in the wake of emerging technologies. Where can we get in front of the wave? Web Surfing in 2022.

In this day and age such reviews are very rare. You're a bicon of hope on the see of all boring reviews :) Hope you'll like our app too :)
